Yeah- Edelbrock seems to suck now. If you look at my latest pictures you might notice a black spacer under the TBI. The fuel injection has been surging so bad it would only run for 6-7 seconds then stall. After months of them blaming every component on the truck I proved to them after the trucks sits for 10-15 minutes and the TBI would heat soak it would surge. I used a heat gun to pre-heat the TBI on a cold engine and it would do it everytime. (Only would heat it to 115 degrees, verified with a IR thermometer). They would "check into it" and then have ignored me for the past 3 weeks.
Once I put in that phenolic spacer it has run much better. But it is cold here and might have problems next summer. I'll deal with that then I guess. TBI only gets up to 72 degrees right now.
So- back to the intake manifold leak. Tired of spending $$$$$$$$$$$$ fixing everything I own lately so was trying to think of other ways to fix or at least lessen my issue. Today I bought a 7 psi radiator cap for the truck. No, not quite correct but out of options. Vehicles in the 60's used 7 psi caps, and before that they used 4 psi.
With less pressure I have dropped the boiling point by 27 degrees. I'm running a 180 degree thermostat and the truck consistently runs at about 175. Maybe less pressure will slow or stop the coolant seep in the manifold.
Wishful thinking maybe- but worth a try.
